Explaining Chemical Reactions: Cell Respiration, Combustion, and Photosynthesis
Goals: 2.4.1-5 (Refer to Unit Map for full details)
Part #1: Describe Chemical Reactions
a. Describe the reactions inputs and outputs for photosynthesis (PS), cell respiration (CR), and
combustion (CO). Use the chemical formulas for inputs and outputs. For example, water = H2O.
PS:
CR:
CO:
Part #2: Compare and Contrast

Using the highlight tool, highlight the similarities between CR and CO in yellow. Use green to highlight
the similarities between CR and PS.
Part #3: Transformation of Inputs & Outputs
a. Chemical equations transform (change) inputs into products. Examine the photosynthesis reaction
that you described in Part #1. Match the input and output that are linked.
In other
words, what specific product is created by each input?
“If the input is…””
“…then the output is.”
“This makes sense because…”
b. Repeat the task for cellular respiration.
“If the input is…””
“…then the output is.”
“This makes sense because…”
